SAFETY FILLING DEVICE FOR TEA-KETILES.

Application filed January 14, 1909.

To all whom it may concern:

Be it known that I, GUY T. BOHAN, a citizen of the United States,residing at Maza, in the county of Towner and State of North Dakota,have invented certain new and useful Improvements in Safety FillingDevices for Tea-Kettles, of which the following is a specification.

This invention relates to a safety filling device for tea kettles, andhas for its object, broadly, the provision of means whereby steam may beprevented from escaping through the intake opening at the top of thekettle, these means not interfering with the operation of filling, andthereby preventing injury to the operator from the scalding efiects ofsteam, while removing the lid or while filling the kettle.

T he invention includes the employment of a secondary receptacle whichmay be removably secured upon the top. of the kettle and which may beconveniently filled with cold \valer while the water in the kettle isboiling, whereby the latter may be filled without exposing the hand ofthe operator to the steam, such device to be reliable in operation andcomprising few and simple parts so that it may be economical inmanufacture.

lVith these and other objects in view the invention presents a novelcombination and arrangement of parts as described herein, pointed out inthe appended claim and as illustrated in the drawing, wherein,

Figure 1 is a side view of a tea kettle provided with a safety fillingdevice embodying my invention. Fig. 2 is a plan view showing the rim ofthe secondary or filling-receptacle, and the rim or flange of the lid,and lugs or recesses thereon, being a sectional view between lines a aand 7) Z) of Fig. 1. Fig. 8 is a plan view of the bottom of the lid.Fig. l: is a sectional view showing a tea kettle with my newly inventedsafety filling device thereon. Fig. 5 is a plan view of the revolubleclosure-plate, the spindle being in section. Fig. 6 is a plan view ofthe bottom of the secondary recep- 'tacle.

Referring now to the drawing for a more particular description of theinvention, numeral 7 indicates the containing-wall of a tea kettlehaving an opening or intake 8 formed in its upper, transverse wall 9,said upper wall preferably having a spiral groove 10 formed at itsupper, open terminal. I pro- Specification of Letters Patent.

Serial No. 472,216.

vide a secondary or filling-receptable 11 comprising a bottom 12 havingan opening 13. This receptacle preferably has a circular side wall 14Lhaving at its lower end the spiral ridge 15 adapted to register withgroove. 10 for securing receptacle 11 upon the kettle. I

Opening 13 is located intermediate the 1 middle and the outer edge ofbottom 12. I

provide the circular closure-plate 17 having a series of perforations 18located near each v other upon a part of its area. Plate 17 is disposedadjacent toand parallel with bottom 12 and is secured at its middle uponor near the bottom of the upright spindle 16, and the lower end of thespindle is pivotally mounted upon and at the middle of bottom 12, andpreferably is secured by nut 19 immediately below said bottom 12. Asthus described plate 17 is rotatable. That part of the area of plate 17occupied by perforations 18 is at a radial distance from spindle 16equal to the radial distance of opening 13 from the spindle, when theparts are assembled, and if the spindle is partly rotated it will causeperforations 18 of plate 17 to register with said opening 13, and if itbe again partly rotated, it is apparent that the blank or unperforatedpart of plate 17 will be presented adjacent to opening 13, therebycausing, substantially, a closure of this opening.

I provide the lid 20, comprising the top or cover 21 having ears 22within which are pivotally mounted the arms 23, and between arms 23 ismounted the handle 21. Cover 21 is provided. with. rim or flange 25which may be seated within wall 1 1, and the cover is provided with acentral opening 26. Flange 25 is provided with recess or slot 27 andwall. 1.4: is provided with the projection or lug 28.

In operation, to fill the kettle, the parts being in the position shownin Fig. 4, lid 20 is raised upwardly, manually, by means of handle 24,the wall of recess 27 at this time, sliding upward upon lug 28; and asthe lid is removed head 29 will traverse opening 26. It will be seenthat receptacle 11 may, at this time, be filled, and injury to the handof the operator from. escaping steam is prac tically eliminated, sinceopenlng 13 is closed. A partial rotation of spindle 16 will cause theperforations to register with opening 13 and the water will pass withinthe kettle.

It will be seen that spindle 16 may be 1o tated while lid 20 is upon thefilling-receptacle, since head 29, at this time, projects exteriorly ofthe lid. lVhen about to fill the kettle, the operator, if steam has beengenerated, rotates head 29 so that a closure is made of opening 13.

By removing the threaded nut 19, plate 17 may be removed from receptacle11, for purpose of conveniently cleaning the parts. To remove receptable11 from the tea kettle proper, it is unscrewed, that is to say, Wall 14of receptacle 11 may be moved circularly to cause spiral ridge 15 topass out of engagement with groove 10, the operator at this timegrasping handl 24. The rim of lid will not. slide circularly upon wall14:, since lug 28 engages within recess or slot 27.

In the use of the herein described tea kettle with the safety deviceattachment thereon, recept-able 11 is very rarely rereadily accomplishedand lid 20 may be quickly removed for the purpose of filling the kettlewith water, and this operation, by i reason of the constructiondescribed, is not attended with the injurious results mentioned.

.Vhile I have explained the device with exactness, the scope of theinvention is considered more broad than the description and I do notlimit myself to specific details, except so far as limited by the claim.

hat I claim as my invention and desire to secure Letters Patent is,

In a device of the character described, the combination with a kettlebody having an 1 opening in the top thereof, a threaded upstandingmember surrounding said opening,

7 a removable casing having threaded engagej ment therewith said casinghaving an open top and having an opening formed through I its bottom, arotatable plate having a series 'of perforations therein, said plateresting upon the bottom of the casing. a closure for said casing and anactuating stem secured to said rotatable plate and projecting throughsaid closure. moved. A closure of opening 13 may be In testimony whereofI have affixed my s1 gnature in presence of two witnesses.
